CVE-2025-46912
📋 TL;DR
A stored Cross-Site Scripting (XSS) vulnerability in Adobe Experience Manager allows low-privileged attackers to inject malicious JavaScript into vulnerable form fields. When victims browse pages containing these fields, their browsers execute the attacker's scripts. This affects Adobe Experience Manager versions 6.5.22 and earlier.

📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Attackers could steal session cookies, perform actions as authenticated users, redirect to malicious sites, or install malware on victim systems.
Likely Case
Session hijacking, credential theft, or defacement of web pages through injected content.
If Mitigated
Limited impact if proper input validation and output encoding are implemented, though risk remains for unpatched systems.
🎯 Exploit Status
Exploitation requires authenticated low-privileged access to inject scripts into vulnerable fields.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 6.5.23 or later
Vendor Advisory: https://helpx.adobe.com/security/products/experience-manager/apsb25-48.html
Restart Required: Yes
Instructions:
1. Backup your AEM instance. 2. Download and apply the latest security update from Adobe's official repository. 3. Restart the AEM service. 4. Verify the update was successful.
🔧 Temporary Workarounds
Input Validation and Output Encoding
allImplement strict input validation and output encoding for all user-controllable form fields.
Content Security Policy (CSP)
allDeploy a strict Content Security Policy to mitigate XSS impact by restricting script execution.
🧯 If You Can't Patch
- Restrict low-privileged user access to vulnerable form fields and components.
- Implement web application firewall (WAF) rules to block XSS payloads.
🔍 How to Verify
Check if Vulnerable:
Check AEM version via the Welcome screen or OSGi console; if version is 6.5.22 or earlier, the system is vulnerable.Check Version:
curl -s http://localhost:4502/libs/granite/core/content/login.html | grep 'AEM 6.5'Verify Fix Applied:
Confirm AEM version is 6.5.23 or later and test form fields for XSS payloads.📡 Detection & Monitoring
Log Indicators:
- Unusual POST requests to form submission endpoints with script tags or JavaScript payloads in parameters.
Network Indicators:
- HTTP requests containing script tags or JavaScript in form field parameters.
SIEM Query:
source="aem_access.log" AND ("<script>" OR "javascript:" OR "onerror=" OR "onload=")
